Saw this BioLite 'Smokeless' Fire Pit
the other day and it seemed interesting. Similar size to some of the firepans out there, a little lighter weight, and with legs 5+ inches high should meet the fire pan restrictons. At $199 it seems pretty spendy at first glance, but I suppose it might have a place in the backyard as well as the river. Know some of the fancy fire pans out there go for about the same price as well.
Not really sure I'm in the market for one of these, but thought I'd share and see if folks had any thoughts. Looks like they've already sold about 11k in a month so there might be something to it.
